Hear the separation wall

These licensed source recordings were AI-separated by StemSlice and excerpted to 30 seconds. User uploads are private and never published.

Hear phrasing without the full arrangement

Use the vocal prediction for transcription, harmony study, and focused listening.

Solo the singer

Hear breaths, harmonies, and phrasing you can't catch in the full mix.

Export for editing

Choose WAV, FLAC, or MP3-320 after the preview shows that the vocal is suitable for the intended edit.

Instrumental included

You get both sides of every split.

Temporary encrypted storage

Files are encrypted in transit and at rest, set to expire 24 hours after job creation, and then removed by automated cleanup.

Know what a vocal stem can contain

Lead, backing parts, reverb, and shared ambience may remain together in a mastered mix.

Isolation helps transcription and pronunciation work

Reducing the backing track makes quiet syllables, breaths, doubles, and phrasing easier to study. Loop a short line, compare it with the original mix, and slow it inside an editor after export if necessary. The isolated vocal can reveal performance detail, but accompaniment bleed should be expected where voice and instruments occupy the same frequencies.

Lead and backing vocals may stay together

A four-stem model predicts a vocal family, not the original multitrack session. Lead, doubles, harmonies, choir parts, and vocal effects can all appear in the vocal stem. That is useful for many covers and remixes, but it is not a promise of separate lead and backing-vocal files.

Evaluate exposed sections before relying on the result

A vocal that sounds clean over a new beat may still reveal artifacts when played alone. Test an exposed intro, a dense chorus, and a sustained final note. Those moments cover different failure modes and make the preview a better guide than judging only the loudest ten seconds.

Treat a vocal stem as a prediction, not a studio multitrack

The output can contain lead, doubles, backing parts, and shared ambience because those elements overlap in the mastered recording. Label the file accurately when sharing it with collaborators, preserve the source reference, and avoid promising a completely dry vocal when the preview still contains production effects.

Use short loops to distinguish bleed from intended ambience

Loop the same syllable with and without the original mix, then listen to the tail after the word ends. A reverb tail may be part of the vocal production, while a repeating guitar or cymbal pattern is more likely accompaniment bleed. This comparison helps avoid destructive cleanup and gives collaborators a clearer description of the remaining artifact.

Credits that do not expire

FAQ

Answers for free limits, formats, privacy, copyright, and download quality.

What does "isolate vocals" mean?

It means extracting just the singing from a song, so the vocal plays alone without the backing music.

Is vocal isolation free here?

Uploading and previewing is free (3 songs a day). Full-quality downloads use credits from $4.9 — no subscription.

How is this different from an acapella extractor?

Same result, different wording: both give you the vocal-only track.

Can I isolate backing vocals or harmonies?

The model targets all vocals as one stem. Separating lead from backing vocals isn't supported yet.

Does it work on podcasts or speech?

It's trained on music. For spoken word over background music it still performs well, but results vary.

What quality can I download?

Lossless WAV, FLAC, or 320kbps MP3.

Is it legal to isolate vocals from a copyrighted song?

The tool is legal; the vocal still belongs to its rights holder. Get permission before commercial use.

Extracted stems remain the property of the original rights holders. Commercial use requires their permission.
